Benelux: Luxembourg

Economic growth in Luxembourg is strong; wages have increased leading to more private consumption. Therefore, the country continues to be an attractive market for prestige brand owners. Changes with respect to the Benelux Convention on Intellectual Property are important to note; for one thing, appeals against decisions of the Benelux Office of Intellectual Property were centralised with the Benelux Court of Justice where previously these had to be filed in appeal courts in Brussels, The Hague or Luxembourg.

/c Law

Laser-focused IT, data protection and IP boutique /c Law is taking the market by storm and cultivating an excellent reputation for specialist expertise and its attentive and personalised service. The firm is the brainchild of Claire Léonelli, a “tough litigator”, seasoned counsellor and keynote speaker. Without dropping a single ball, she has handled a diverse and demanding workload recently; she has untangled myriad licensing issues as part of an enforcement effort for a fashion brand; argued appeals before the Luxembourg Court of Appeal for a bank; and handled oppositions for a leading real estate firm.

Allen & Overy

An IP pioneer and practice leader in Luxembourg, Allen & Overy impresses at every turn. When it comes to brands, nothing is off limits for the set, which has all the expertise you could want in trademarks and adjacent areas, including advertising, unfair competition, data protection, internet and media law. The revered leader of the team, Katia Manhaeve, is dedicated to her clients but also does much for the greater good of all IP stakeholders. She straddles the contentious/non-contentious divide artfully and is an authoritative all-rounder with broad international horizons. A highlight of her exciting recent practice was a General Court and European Court of Justice appeal win for fashion retailer Cactus, which clarified the scope of application of the IP Translator and Praktiker Bau decisions.

Arendt & Medernach

An ally not just in law but in business, Arendt & Medernach is appreciated by clients for the breadth of its legal, regulatory, tax and advisory services. The organisation’s IP experts demonstrate particularly strong project management expertise when establishing and monetising trademark portfolios. Sophie Wagner-Chartier runs the IP, communication and technology practice.

Decker & Braun

Influential law firm Decker & Braun is a standard setter in terms of efficient, commercially oriented legal services. On the IP front, the team moves swiftly and smartly to facilitate resolutions to complicated disputes. Nicolas Decker and Marianne Decker are both masters in this regard. When they speak it is obvious that they have carefully thought through their arguments, so people sit up and listen. They put the case, the subject matter and their clients first and get right to the heart of matters in the most practical way.

NautaDutilh Avocats Luxembourg Sàrl

The team at NautaDutilh in Luxembourg understands that trademark rights are crucial business assets and works its socks off to give clients commercial bite in their markets. Holistic in its approach to brands, the set exploits abundant experience in advertising, trade secret and unfair competition law in a way that adds immense value. IP litigation is meat and drink to the group, but trademark restructuring for tax purposes is another field in which the side is exceptional. Vincent Wellens occupies the NautaDutilh driver’s seat, a “top specialist” and trusted partner for many sophisticated international clients. His in-house experience shines through in his business-centric advice, which ranges over IP, technology, unfair competition, data protection and e-commerce law. In terms of trademark work, securing a pan-EU injunction against Coach acting on behalf of Fendi is a notable recent highlight.


Wildgen has a particularly excellent reputation in finance, tax and commercial law, but it also practices in intellectual property with finesse. Emmanuelle Ragot heads the data protection, IP, technology and media group and runs W4 Innovation – the firm’s unique legal hub for start-ups. Litigating is what she is best known for in IP circles, but she does sterling transactional work too. Leveraging an excellent network of contacts abroad she truly thinks internationally when it comes to devising IP strategies.
